HP Industrial Ink

What is HP Industrial Ink, and how does Thermal Inkjet (TIJ) technology work?

HP Industrial Ink refers to a specialized range of high-performance cartridges and fluids engineered specifically for demanding, high-speed manufacturing environments. Unlike standard office printers, these industrial inks are formulated to dry instantly and stick permanently to a massive variety of challenging surfaces. The technology behind this is called Thermal Inkjet (TIJ). It is a highly precise, non-contact printing method that works by using heat to generate tiny bubbles inside the printhead nozzle. The pressure from these expanding bubbles instantly ejects microscopic ink droplets directly onto your product packaging.Because TIJ is a completely non-contact printing method, it eliminates the wear-and-tear, maintenance, and mess associated with older, contact-based stamping or mechanical printing systems.

At Daemon Print Supplies, we have leveraged our deep expertise in coding and marking to contribute directly to the evolution of this technology. By pairing original HP industrial hardware with innovative, next-generation inks (like the Kao Collins and General Ink portfolios), we help facilities achieve crisp, high-contrast barcodes and batch codes on everything from porous cardboard to slick plastic films—all with virtually zero maintenance downtime.

What materials can Thermal Inkjet (TIJ) inks print on, and how do I know which ink type I need?

Thermal Inkjet (TIJ) systems are incredibly versatile and can print on almost any industrial material – including paper, cardboard, plastics, metals, textiles, and coated labels.

However, to get a dark, crisp print that won't smudge, you must match your specific material to the correct ink type. Industrial inks generally fall into two simple categories:

• Water-Based Inks (Best for Porous Materials): These inks are designed to soak into the surface to dry. They are the ideal choice for everyday packaging like standard cardboard boxes, paper outer cases, envelopes, paper bags, and textiles.
• Solvent-Based Inks (Best for Non-Porous Materials): These inks are designed to stick to slick, non-absorbent surfaces and dry completely through fast evaporation. You must use a solvent ink if you are printing on plastic films (like PE, PET, and PP), rigid PVC, aluminum foil, varnished or UV-coated boxes, and degreased metals.

Using the wrong ink – like putting a water-based ink onto a glossy plastic film – will result in the ink pooling and smudging instantly.

If you are switching packaging materials or are unsure which formulation will give you the best adhesion and dry time, contact the Daemon Print Supplies team. We regularly test customer material samples in our lab to guarantee you get the perfect ink match for your production line.

Can I use solvent-based TIJ black inks on primary or secondary food packaging?

Yes, but you must select an ink specifically formulated to comply with European food contact guidelines, and understand where the ink is being applied. In Europe, food safety laws (EC No 1935/2004 and the strict EuPIA Charter) require that chemical substances from packaging materials must never migrate into food products in a way that risks human health or changes the food's taste or odor.

Here is how you can safely deploy TIJ solvent inks in your food production line:

• Secondary Food Packaging (Outer Boxes and Cases): This is the safest and most common application. Standard, high-performance solvent black inks can be used to print dynamic barcodes and batch codes on outer cardboard or protective film layers, provided there is no direct risk of "set-off" (ink transferring from the outside of one package to the inside of another during stacking).
• Primary Food Packaging (Direct or Near-Food Contact): If you are printing directly onto the film, foil, or pouch holding the food, you cannot use traditional solvent inks. Many older formulas contain restricted raw materials or trace solvents that can easily migrate through plastic thin films.

To safely print on primary packaging or slick films, you need a modern, future-proof solvent ink like Kao Collins SIGMA+ (TSK3646). Because it is strictly Non-CMR and 100% PFAS-Free, it complies fully with the latest EuPIA Raw Material Selection Charter and REACH SVHC restrictions. It gives you the aggressive adhesion and 3-second dry times required for plastic food packaging, without introducing regulatory or chemical migration liabilities into your supply chain.

If you need a formal Declaration of Compliance (DoC) or Statement of Composition for your food safety audits, contact the Daemon Print Supplies team. We can provide the necessary documentation to keep your line fully certified.

Why are European supply chains transitioning away from traditional solvent inks to Non-CMR and PFAS-Free formulations?

European manufacturing operations face strict regulatory shifts driven by the EU's updated CLP (Classification, Labelling and Packaging) Regulations and the PPWR (Packaging and Packaging Waste Regulation). Traditional solvent-based black inks frequently rely on chemical compounds now targeted for phase-out due to worker exposure and environmental longevity risks.

To protect your business from compliance liabilities, next-generation formulations must meet two crucial benchmarks:

• Non-CMR: The ink contains zero chemical agents classified as Carcinogenic, Mutagenic, or Toxic for Reproduction. This completely eliminates heavy reporting burdens and shields production floor operators from chemical handling hazards.
• PFAS-Free: Transitioning to inks free from per- and polyfluoroalkyl substances ("forever chemicals") satisfies tightening legal restrictions targeting intentional PFAS usage across commercial packaging, plastic films, and labeling materials.

As the leading independent supplier, Daemon Print Supplies actively audits our commercial portfolio to provide seamless, drop-in regulatory solutions – such as Kao Collins SIGMA+ (TSK3646) – guaranteeing full EuPIA and REACH SVHC compliance without sacrificing print performance, rapid dry times, or structural adhesion.
